Given numbers are 952, 689, 645, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(952, 689) = 655928
GCD(952, 689) = ( 952 x 689 ) / 655928
= 952 / 689
= 952
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 952, 689, 645, 781 is 1
