Given numbers are 949, 772, 776, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(949, 772) = 732628
GCD(949, 772) = ( 949 x 772 ) / 732628
= 949 / 772
= 949
Step2:
LCM(1, 776) = 776
GCD(1, 776) = ( 1 x 776 ) / 776
= 1 / 776
= 1
Step3:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 949, 772, 776, 661 is 1
