Given numbers are 840, 140, 262, 345
The list of prime factors of all numbers are
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 140 are 2 x 2 x 5 x 7
Prime factors of 262 are 2 x 131
Prime factors of 345 are 3 x 5 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 140, 262, 345
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 140) = 840
GCD(840, 140) = ( 840 x 140 ) / 840
= 840 / 140
= 840
Step2:
LCM(140, 262) = 18340
GCD(140, 262) = ( 140 x 262 ) / 18340
= 140 / 262
= 140
Step3:
LCM(2, 345) = 690
GCD(2, 345) = ( 2 x 345 ) / 690
= 2 / 345
= 2
So, Greatest Common Divisor of 840, 140, 262, 345 is 1
