Given numbers are 672, 896, 635, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(672, 896) = 2688
GCD(672, 896) = ( 672 x 896 ) / 2688
= 672 / 896
= 672
Step2:
LCM(224, 635) = 142240
GCD(224, 635) = ( 224 x 635 ) / 142240
= 224 / 635
= 224
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 672, 896, 635, 820 is 1
