Given numbers are 608, 628, 688, 647
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(608, 628) = 95456
GCD(608, 628) = ( 608 x 628 ) / 95456
= 608 / 628
= 608
Step2:
LCM(4, 688) = 688
GCD(4, 688) = ( 4 x 688 ) / 688
= 4 / 688
= 4
Step3:
LCM(4, 647) = 2588
GCD(4, 647) = ( 4 x 647 ) / 2588
= 4 / 647
= 4
So, Greatest Common Divisor of 608, 628, 688, 647 is 1
