Given numbers are 660, 906, 176, 647
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 906) = 99660
GCD(660, 906) = ( 660 x 906 ) / 99660
= 660 / 906
= 660
Step2:
LCM(6, 176) = 528
GCD(6, 176) = ( 6 x 176 ) / 528
= 6 / 176
= 6
Step3:
LCM(2, 647) = 1294
GCD(2, 647) = ( 2 x 647 ) / 1294
= 2 / 647
= 2
So, Greatest Common Divisor of 660, 906, 176, 647 is 1
