GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(928, 440) = 51040
GCD(928, 440) = ( 928 x 440 ) / 51040
= 928 / 440
= 928
Step2:
LCM(8, 870) = 3480
GCD(8, 870) = ( 8 x 870 ) / 3480
= 8 / 870
= 8
Step3:
LCM(2, 670) = 670
GCD(2, 670) = ( 2 x 670 ) / 670
= 2 / 670
= 2
So, Greatest Common Divisor of 928, 440, 870, 670 is 2
