Given numbers are 663, 870, 352, 628
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 870) = 192270
GCD(663, 870) = ( 663 x 870 ) / 192270
= 663 / 870
= 663
Step2:
LCM(3, 352) = 1056
GCD(3, 352) = ( 3 x 352 ) / 1056
= 3 / 352
= 3
Step3:
LCM(1, 628) = 628
GCD(1, 628) = ( 1 x 628 ) / 628
= 1 / 628
= 1
So, Greatest Common Divisor of 663, 870, 352, 628 is 1
