GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 128) = 17792
GCD(278, 128) = ( 278 x 128 ) / 17792
= 278 / 128
= 278
Step2:
LCM(2, 412) = 412
GCD(2, 412) = ( 2 x 412 ) / 412
= 2 / 412
= 2
Step3:
LCM(2, 970) = 970
GCD(2, 970) = ( 2 x 970 ) / 970
= 2 / 970
= 2
So, Greatest Common Divisor of 278, 128, 412, 970 is 2
