Given numbers are 840, 953, 207, 351
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 953) = 800520
GCD(840, 953) = ( 840 x 953 ) / 800520
= 840 / 953
= 840
Step2:
LCM(1, 207) = 207
GCD(1, 207) = ( 1 x 207 ) / 207
= 1 / 207
= 1
Step3:
LCM(1, 351) = 351
GCD(1, 351) = ( 1 x 351 ) / 351
= 1 / 351
= 1
So, Greatest Common Divisor of 840, 953, 207, 351 is 1
