Given numbers are 642, 126, 89, 563
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 126) = 13482
GCD(642, 126) = ( 642 x 126 ) / 13482
= 642 / 126
= 642
Step2:
LCM(6, 89) = 534
GCD(6, 89) = ( 6 x 89 ) / 534
= 6 / 89
= 6
Step3:
LCM(1, 563) = 563
GCD(1, 563) = ( 1 x 563 ) / 563
= 1 / 563
= 1
So, Greatest Common Divisor of 642, 126, 89, 563 is 1
