Given numbers are 948, 639, 435, 878
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(948, 639) = 201924
GCD(948, 639) = ( 948 x 639 ) / 201924
= 948 / 639
= 948
Step2:
LCM(3, 435) = 435
GCD(3, 435) = ( 3 x 435 ) / 435
= 3 / 435
= 3
Step3:
LCM(3, 878) = 2634
GCD(3, 878) = ( 3 x 878 ) / 2634
= 3 / 878
= 3
So, Greatest Common Divisor of 948, 639, 435, 878 is 1
