Given numbers are 642, 324, 49, 694
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 324) = 34668
GCD(642, 324) = ( 642 x 324 ) / 34668
= 642 / 324
= 642
Step2:
LCM(6, 49) = 294
GCD(6, 49) = ( 6 x 49 ) / 294
= 6 / 49
= 6
Step3:
LCM(1, 694) = 694
GCD(1, 694) = ( 1 x 694 ) / 694
= 1 / 694
= 1
So, Greatest Common Divisor of 642, 324, 49, 694 is 1
