Given numbers are 645, 781, 124, 929
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 781) = 503745
GCD(645, 781) = ( 645 x 781 ) / 503745
= 645 / 781
= 645
Step2:
LCM(1, 124) = 124
GCD(1, 124) = ( 1 x 124 ) / 124
= 1 / 124
= 1
Step3:
LCM(1, 929) = 929
GCD(1, 929) = ( 1 x 929 ) / 929
= 1 / 929
= 1
So, Greatest Common Divisor of 645, 781, 124, 929 is 1
