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 755 are 5 x 151
Prime factors of 141 are 3 x 47
Prime factors of 493 are 17 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 755, 141, 493
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 755) = 126840
GCD(840, 755) = ( 840 x 755 ) / 126840
= 840 / 755
= 840
Step2:
LCM(5, 141) = 705
GCD(5, 141) = ( 5 x 141 ) / 705
= 5 / 141
= 5
Step3:
LCM(1, 493) = 493
GCD(1, 493) = ( 1 x 493 ) / 493
= 1 / 493
= 1
So, Greatest Common Divisor of 840, 755, 141, 493 is 1
