Given numbers are 670, 431, 368, 987
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 431) = 288770
GCD(670, 431) = ( 670 x 431 ) / 288770
= 670 / 431
= 670
Step2:
LCM(1, 368) = 368
GCD(1, 368) = ( 1 x 368 ) / 368
= 1 / 368
= 1
Step3:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
So, Greatest Common Divisor of 670, 431, 368, 987 is 1
