Given numbers are 278, 156, 473, 668
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 156) = 21684
GCD(278, 156) = ( 278 x 156 ) / 21684
= 278 / 156
= 278
Step2:
LCM(2, 473) = 946
GCD(2, 473) = ( 2 x 473 ) / 946
= 2 / 473
= 2
Step3:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
So, Greatest Common Divisor of 278, 156, 473, 668 is 1
