Given numbers are 738, 688, 424, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(738, 688) = 253872
GCD(738, 688) = ( 738 x 688 ) / 253872
= 738 / 688
= 738
Step2:
LCM(2, 424) = 424
GCD(2, 424) = ( 2 x 424 ) / 424
= 2 / 424
= 2
Step3:
LCM(2, 621) = 1242
GCD(2, 621) = ( 2 x 621 ) / 1242
= 2 / 621
= 2
So, Greatest Common Divisor of 738, 688, 424, 621 is 1
