Given numbers are 355, 643, 917, 534
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(355, 643) = 228265
GCD(355, 643) = ( 355 x 643 ) / 228265
= 355 / 643
= 355
Step2:
LCM(1, 917) = 917
GCD(1, 917) = ( 1 x 917 ) / 917
= 1 / 917
= 1
Step3:
LCM(1, 534) = 534
GCD(1, 534) = ( 1 x 534 ) / 534
= 1 / 534
= 1
So, Greatest Common Divisor of 355, 643, 917, 534 is 1
