Given numbers are 654, 207, 642, 811
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(654, 207) = 45126
GCD(654, 207) = ( 654 x 207 ) / 45126
= 654 / 207
= 654
Step2:
LCM(3, 642) = 642
GCD(3, 642) = ( 3 x 642 ) / 642
= 3 / 642
= 3
Step3:
LCM(3, 811) = 2433
GCD(3, 811) = ( 3 x 811 ) / 2433
= 3 / 811
= 3
So, Greatest Common Divisor of 654, 207, 642, 811 is 1
