Given numbers are 670, 215, 692, 557
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 215) = 28810
GCD(670, 215) = ( 670 x 215 ) / 28810
= 670 / 215
= 670
Step2:
LCM(5, 692) = 3460
GCD(5, 692) = ( 5 x 692 ) / 3460
= 5 / 692
= 5
Step3:
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
= 1 / 557
= 1
So, Greatest Common Divisor of 670, 215, 692, 557 is 1
