GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(896, 860) = 192640
GCD(896, 860) = ( 896 x 860 ) / 192640
= 896 / 860
= 896
Step2:
LCM(4, 646) = 1292
GCD(4, 646) = ( 4 x 646 ) / 1292
= 4 / 646
= 4
Step3:
LCM(2, 988) = 988
GCD(2, 988) = ( 2 x 988 ) / 988
= 2 / 988
= 2
So, Greatest Common Divisor of 896, 860, 646, 988 is 2
