Given numbers are 128, 917, 661, 824
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(128, 917) = 117376
GCD(128, 917) = ( 128 x 917 ) / 117376
= 128 / 917
= 128
Step2:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
Step3:
LCM(1, 824) = 824
GCD(1, 824) = ( 1 x 824 ) / 824
= 1 / 824
= 1
So, Greatest Common Divisor of 128, 917, 661, 824 is 1
