Given numbers are 654, 780, 311, 692
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(654, 780) = 85020
GCD(654, 780) = ( 654 x 780 ) / 85020
= 654 / 780
= 654
Step2:
LCM(6, 311) = 1866
GCD(6, 311) = ( 6 x 311 ) / 1866
= 6 / 311
= 6
Step3:
LCM(1, 692) = 692
GCD(1, 692) = ( 1 x 692 ) / 692
= 1 / 692
= 1
So, Greatest Common Divisor of 654, 780, 311, 692 is 1
