GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 456) = 48792
GCD(428, 456) = ( 428 x 456 ) / 48792
= 428 / 456
= 428
Step2:
LCM(4, 667) = 2668
GCD(4, 667) = ( 4 x 667 ) / 2668
= 4 / 667
= 4
Step3:
LCM(1, 920) = 920
GCD(1, 920) = ( 1 x 920 ) / 920
= 1 / 920
= 1
So, Greatest Common Divisor of 428, 456, 667, 920 is 1
