Given numbers are 142, 488, 643, 357
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 488) = 34648
GCD(142, 488) = ( 142 x 488 ) / 34648
= 142 / 488
= 142
Step2:
LCM(2, 643) = 1286
GCD(2, 643) = ( 2 x 643 ) / 1286
= 2 / 643
= 2
Step3:
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
= 1 / 357
= 1
So, Greatest Common Divisor of 142, 488, 643, 357 is 1
