Given numbers are 688, 420, 504, 674
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 420) = 72240
GCD(688, 420) = ( 688 x 420 ) / 72240
= 688 / 420
= 688
Step2:
LCM(4, 504) = 504
GCD(4, 504) = ( 4 x 504 ) / 504
= 4 / 504
= 4
Step3:
LCM(4, 674) = 1348
GCD(4, 674) = ( 4 x 674 ) / 1348
= 4 / 674
= 4
So, Greatest Common Divisor of 688, 420, 504, 674 is 2
