Given numbers are 124, 396, 801, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(124, 396) = 12276
GCD(124, 396) = ( 124 x 396 ) / 12276
= 124 / 396
= 124
Step2:
LCM(4, 801) = 3204
GCD(4, 801) = ( 4 x 801 ) / 3204
= 4 / 801
= 4
Step3:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 124, 396, 801, 661 is 1
