Given numbers are 640, 358, 202, 107
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 358) = 114560
GCD(640, 358) = ( 640 x 358 ) / 114560
= 640 / 358
= 640
Step2:
LCM(2, 202) = 202
GCD(2, 202) = ( 2 x 202 ) / 202
= 2 / 202
= 2
Step3:
LCM(2, 107) = 214
GCD(2, 107) = ( 2 x 107 ) / 214
= 2 / 107
= 2
So, Greatest Common Divisor of 640, 358, 202, 107 is 1
