Steps to Calculate GCD of 298, 647, 942, 615 using LCM Formula
Given numbers are 298, 647, 942, 615
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(298, 647) = 192806
GCD(298, 647) = ( 298 x 647 ) / 192806
= 298 / 647
= 298
Step2:
LCM(1, 942) = 942
GCD(1, 942) = ( 1 x 942 ) / 942
= 1 / 942
= 1
Step3:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
So, Greatest Common Divisor of 298, 647, 942, 615 is 1
