Given numbers are 642, 467, 925, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 467) = 299814
GCD(642, 467) = ( 642 x 467 ) / 299814
= 642 / 467
= 642
Step2:
LCM(1, 925) = 925
GCD(1, 925) = ( 1 x 925 ) / 925
= 1 / 925
= 1
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 642, 467, 925, 781 is 1
