GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 699) = 35649
GCD(153, 699) = ( 153 x 699 ) / 35649
= 153 / 699
= 153
Step2:
LCM(3, 640) = 1920
GCD(3, 640) = ( 3 x 640 ) / 1920
= 3 / 640
= 3
Step3:
LCM(1, 957) = 957
GCD(1, 957) = ( 1 x 957 ) / 957
= 1 / 957
= 1
So, Greatest Common Divisor of 153, 699, 640, 957 is 1
