Given numbers are 642, 306, 397, 746
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 306) = 32742
GCD(642, 306) = ( 642 x 306 ) / 32742
= 642 / 306
= 642
Step2:
LCM(6, 397) = 2382
GCD(6, 397) = ( 6 x 397 ) / 2382
= 6 / 397
= 6
Step3:
LCM(1, 746) = 746
GCD(1, 746) = ( 1 x 746 ) / 746
= 1 / 746
= 1
So, Greatest Common Divisor of 642, 306, 397, 746 is 1
